Printing the parts¶

Material and settings¶

PETG for every part but the TPU jaw pads. The repository's print table is one line, and it is the whole rule: use 25 % infill for all (Print_table.md). Supports where your slicer asks for them; the body prints on its back.

The files¶

Variant	Folders in STEP files
every gripper	`Common parts`: the coupler plate and ring cover (or `ring_cover-PAROL6`), the camera mount and lid, the jaw blocker, the stepper spacer, the connector lid
your rail	`Linear rail dependant parts/<rail>`: the body and the two jaw carriers
your stepper	`Stepper dependant parts/<stepper>`: the stepper cover, and the spacer for the 21.5 mm stepper
the jaws	`Gripper jaws attachment`: one of the designs, mirrored for the other side

The Print files folder has the same parts as 3MF, ready to slice.

The jaws¶

Two kinds, both in Gripper jaws attachment; mirror the file in the slicer for the other side, except the solid jaw, which has a mirrored file:

TPU jaws (recommended): a PETG body, MSG_JAW_TPU_GLUE, and a soft TPU pad printed separately and glued on. The pad deforms around the object for a gentler, surer grip. Print the pad with 16 % infill, no top or bottom layers and 2 walls for the softest grip; the body with the normal settings.
Solid jaws: MSG_solid_jaw and MSG_solid_jaw_mirror in one piece, or MSG_JAW_HOLLOW for a two-colour print; MSG_JAW_TPU_GLUE prints solid too.

Figure 1: The TPU jaw in the slicer: the PETG body (orange) and the TPU pad (green) as separate parts.

Figure 2: Two TPU pads sliced with the pad's settings: the honeycomb infill shows, with no top layer.

Gluing the pad on, its orientation and the sponge tape for the gripping faces are in Jaws; the repository's jaw guide is the original.
